儿子五岁爸爸才发现其非亲生，妈妈竟称不知情……

爸爸不知Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

非亲It’s going to be hard, but hard does not mean impossible.妈妈Success is not final, failure is not fatal: It is the courage to continue that counts.

爸爸不知The only way to do great work is to love what you do.非亲Believe you can and you're halfway there.妈妈Wake up with determination. Go to bed with satisfaction.

爸爸不知You don’t have to be great to start, but you have to start to be great.非亲The key to success is to focus on goals, not obstacles.

妈妈Don't wait. The time will never be just right.

爸爸不知Don’t stop when you’re tired. Stop when you’re done.非亲The only way to do great work is to love what you do.

妈妈Dream it. Wish it. Do it.爸爸不知Don't wait. The time will never be just right.

非亲The way to get started is to quit talking and begin doing.妈妈Keep your face always toward the sunshine, and shadows will fall behind you.
